-
An iron-catalyst system FeCl3-Phen-Al(i-Bu)3 for butadiene polymerization has been studied. The results of magnetic susceptibility and UV-Vis spectra measurements indicated that a high-spin complex FeCl3·(EA)2 was formed from FeCl3 and ethyl acetate(EA). The presence of o-phenanthroline(Phen) stabilizes Fe(Ⅱ),markedly reducing the ferromagnetism of the catalyst system.
